Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
For mounting to the edge of a pool above the normal water level of the pool, a device for urging floating debris on the water surface toward a skimmer having an opening at the normal waterline, said device comprising, an elongate tubular arm having: a proximal end zone including means to connect to a waterflow supply through the arm to the distal end zone, means to mount the proximal end zone to the pool edge, said tubular arm including an intermediate zone extending outwardly and downwardly from said proximal end zone, and having a distal end zone below the proximal end zone and above the normal waterline of the pool, and said distal end zone having an opening facing toward said proximal end zone, said means to mount including a base and fastener means to connect the base to the pool edge, and vertical pivot means connecting the proximal end zone of the tubular arm to said base to permit a swinging movement of the arm about the axis of said pivot means.
Claim 2
Dependent Claim
173 words
For mounting to the edge of a pool above the normal water level of the pool, a device for urging floating debris on the water surface toward a skimmer having an opening at the normal waterline, said device comprising, an elongate tubular arm having: a proximal end zone including means to connect to a waterflow supply through the arm to the distal end zone, means to mount the proximal end zone to the pool edge, said tubular arm including an intermediate zone extending outwardly and downwardly from said proximal end zone, and having a distal end zone below the proximal end zone and above the normal waterline of the pool, and said distal end zone having an opening facing toward said proximal end zone, said means to mount including a base and fastener means to connect the base to the pool edge, and vertical pivot means connecting the proximal end zone of the tubular arm to said base to permit a swinging movement of the arm about the axis of said pivot means.
Claim 3
Dependent Claim
21 words
The device as set forth in claim 1 wherein said means to mount includes a fitting on the proximal end zone.
Claim 4
Dependent Claim
30 words
The device as set forth in claim 1 wherein float means are provided for the distal end zone and means to connect the float means to the distal end zone.
Claim 5
Dependent Claim
21 words
The device as set forth in claim 3 wherein said means to mount includes a fitting on the proximal end zone.
Claim 6
Dependent Claim
32 words
The device as set forth in claim 2 wherein said pivot means extends downwardly from said fitting and including means to captivate the pivot means for rotation with respect to said base.
Claim 7
Dependent Claim
44 words
The device as set forth in claim 5 wherein said base includes a dome-shaped hollow in a bottom surface thereof comprising said means to captivate, a transverse groove in a top surface thereof and a through hole, bisecting said groove, opening into said hollow.
Claim 8
Dependent Claim
65 words
The device as set forth in claim 6 wherein said pivot means comprises a pivot pin extending downwardly through said through hole from said fitting and into said hollow, and a nut engaged on a screw-threaded lower end of said pivot pin, with said hollow, in a position to permit a limited amount of vertical movement of said fitting and arm relative to said base.
Claim 9
Dependent Claim
34 words
The device as set forth in claim 7 including a transverse rib on the bottom of said fitting, normally engaged in said groove in a first position and disengaged therefrom in a second position.
Claim 10
Dependent Claim
30 words
The device as set forth in claim 8 wherein said rib is generally triangular in cross sectional configuration to define a bottom knife edge to engage in said transverse groove.
